What procedure will achieve this result? Lower cheek/jowl lift/V-line surgery? (Photos)

For a more defined jawline to strengthen your profile (and help prevent the dreaded jawline "jowl" sagging), we use injectable fillers like Revanesse Versa - a filler known to limit swelling and give subtle, soft enhancements - or Radiesse. Using a cannula to limit pain and swelling, we inject on the bone in strategic points to get more lift and shaping, resulting in a more contoured lower face and defined, structured jawline. I would suggest getting a formal evaluation with a facial sculpting expert. Best, Dr. Emer

Rather than experiment with relatively expensive, faddish "bells and whistles" energy-based devices that are much more heavily supported by marketing hype than any hard science, you may wish to consult an experienced board certified cosmetic dermatologist about the use of robust HA fillers. in truly experienced hands, these may be used to augment the upper, outer cheeks to create a more desirable, feminine heart-shaped, oval face. They may be used to straighten jawline jowls and create a more well defined jawline. What's more, the results of these treatments, unlike with energy devices (if they help at all, that is), are typically seen immediately and elicit an on-the-spot "Wow!" reaction. Hope this helps. Best of luck.

You will likely have the best results from a combination of treatments. You can consider Botox to the masseter muscles to slim the jawline. Filler such as Juvederm Volux can then be used to define jaw contours. Morpheus8 treatments will address overall skin tone and texture.
